Rocket Concepts
A rocket launches successfully and recovery system deploys as intended. However, the shock chords rip and the transition breaks due to forces from the ejection motor. What is the first thing that you do? Why?
A process you conduct to determine the performance of your rocket
a simulation
What is the target altitude for the competition?
835 ft
Material used to mount the fins to the lower body tube
epoxy
The name of the bolt that the shock chords tie on to
eye bolt
what must a rocket have in order to conduct a simulaton?
body tube and motor
what is the target time frame for the competition?
41-44 seconds
tools used to precisely measure length
calipers
True or false
Energy can be created and can be destroyed
false
The point where the resultant of all aerodynamic forces meet
center of pressure
What is the most important parameter to take notice of when building a rocket of any kind?
stability
What is required of the upper and body tubes?
they must be different diameters
the component used to keep the lower and upper body tube in place
transition
Thermal energy is potential or kinetic energy?
kinetic
Location of your launch lugs will affect which parameter of the rocket?
Stability
The option used to change the displayed units of rocksim
preferences
Minimum length for the rocket?
25.6 inches
motor cap
mass x acceleration
Drag coefficient of an elliptical nose cone is 0.565.
Drag coefficient of a conical nose cone is 0.7. Which nose cone will give you a higher altitude?
Elliptical nose cone
BONUS X10
What type of numerical analysis method is used to calculate RockSim parameters in the simulations?
Runge-Kutta
Maximum weight allowed for a rocket
650g
Why would you used 3 screws instead of 2 to mount the nose cone to the upper body tube
two screws cannot symmetrical withstand the forces of launch. The nose cone will tilt with only 2 screws
What is the fastest speed in the universe?
speed of light
